Configuring Tableau and ODBC

Configuring Tableau and ODBC

Hello All,

 

In this blog we will see how we can configure Tableau and ODBC on your system.

Tableau is the most popular data visualization tool which is used widely to visualize the data. You can discover and share the insights that can change the business value.

 

Data visualization is a tool used by all data scientists which help them communicate with their end-users or clients. The result of all the data interpretation is not immediately coherent to the users who do not directly deal with the data. Data visualization acts like that connectivity point and makes users appreciate the occurrence of the data analysis. And, Tableau is one of the best Data visualization software/tools which is used by every other business now.

 

Tableau is a visual analytics program modifying the way we use data to solve problems by enabling oneself and businesses to make the most of their data.

Tableau can perform below tasks.

 

1.   Tracking budgeting expense

2.   Sales data analysis

3.   User density monitoring

4.   Categorizing and sub-categorizing data

5.   Consumer segmenting

 

We will go through all the steps to configure it with your Kerberos and your Hadoop cluster. Once its connected and configured properly you will be able to visualize the table data in Tableau which will help you to analyse your data so that you can take outcome of it.

 

Purpose:

 

This Page depicts the Process of Configuring Tableau and ODBC on the System.

 

Process:

Step 1: Install ODBC data sources 64 Bit  on your system.

Step 2: Install Tableau

Step 3: Install MIT Kerberos on your system.

Step 4:  Create a directory in your C folder For example as Temp1

Step 5: Open System environmental variables. " Right click on My PC→ properties→ Advanced system settings →Environmental variables→System variables→ New→Name:KRB5CCNAME, Value: C:\Temp_1\krb5cache"

Step 6: Go to C:\ProgramData\MIT\Kerberos5 and insert the below content itno krb5 file. (you can take this from any of you server krb5.conf file)

[libdefaults]

  renew_lifetime = 7d

  forwardable = true

  default_realm = ADS.<DOMAIN>.COM

  ticket_lifetime = 24h

  dns_lookup_realm = false

  dns_lookup_kdc = false

  default_ccache_name = /tmp/krb5cc_%{uid}

  #default_tgs_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5

  #default_tkt_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5

[domain_realm]

  .connected.company.com = ADS.<DOMAIN>.COM

 

[logging]

  default = FILE:/var/log/krb5kdc.log

  admin_server = FILE:/var/log/kadmind.log

  kdc = FILE:/var/log/krb5kdc.log

[realms]

  ADS.<DOMAIN>.COM = {

    admin_server = ads.azure.company.com

    kdc = ads.azure.company.com

  }

Step 7: Restart the system

 

Step 8: Open MIT Kerberos and generate ticket using your credentials.

Once you get the ticket then go to C:\Temp_1 and you should have krb5cache file in it.

 

Step 9: Open ODBC and go to system DNS  and select sample

 Hortonworks and configure and fill the details

 

Step 10: Click on HTT Options and add the HTTP path as below

 

Step 11: Click on SSL options and fill the details as shown below

 

Step 12: Click on advanced options and select native query.Click on test → Once test is successful

click on ok as shown below.

 

Step 13: Open Tableau→Click on more and search for odbc

 

Step 14: Select ODBC and select DSN and in the drop down choose the ODBC

 connection which we created on ODBC. Click on connect. You will be able to connect to tableau

 thank you!!!


let us know in comment section if you face any issue while configuring it.


Thank you !! Example HTML page Pleaes provide your valuable feedback.

Roadmap to DevOps

    DevOps is nothing but the combination of process and philosophies which contains four basic component culture, collaboration, tools, and practices. In return, this gives a good automated system and infrastructure which helps an organisation to deliver a quality and reliable build. The beauty of this culture is it enables a quality for organizations to better serve their customers and compete more effectively in the market and also add some promised benefits which include confidence and trust, faster software releases, ability to solve critical issues quickly, and better manage unplanned work.   1. What are the tasks of a DevOps Engineer? Design, build, test and deploy scalable, distributed systems from development through production Manage the code repository(such as Git, SVN, BitBucket, etc.) including code merging and integrating, branching and maintenance and remote repository management Manage, configure and maintain infra...

Ansible

  Ansible is an open-source software provisioning, configuration management, and application-deployment tool. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. It includes its own declarative language to describe system configuration. Ansible was written by Michael DeHaan and acquired by Red Hat in 2015. Ansible is agentless, temporarily connecting remotely via SSH or Windows Remote Management (allowing remote PowerShell execution) to do its tasks. Platform support Control machines have to be a Linux/Unix host (for example SUSE Linux Enterprise, Red Hat Enterprise Linux, Debian, CentOS, macOS, BSD, Ubuntu, and Python 2.7 or 3.5 is required. Managed nodes, if they are Unix-like, must have Python 2.4 or later. For managed nodes with Python 2.5 or earlier, the python-simplejson package is also required. Since version 1.7, Ansible can also manage Windows nodes. In this case, native PowerShell remoting supported by the WS-Managemen...
